I have found attitude used to refer to the means of closure after accidental arterial catherization (though I realize we are not looking at accidents here):

QUELLE ATTITUDE ADOPTER EN CAS DE PONCTION ARTÉRIELLE?
L’attitude à adopter en cas de cathétérisme artériel accidentel est un sujet rarement abordé dans la littérature et il n’existe pas, à notre connaissance, de recommandations fondées sur les preuves. Trois attitudes sont possibles :
A.Retrait du cathéter et compression du site de la ponction artérielle. Cette attitude, expose à des complications immédiate et tardives (pseudoanévrismes, fistules) dont l’incidence est difficile à préciser. Elle est vivement déconseillée en cas de thrombocytopénie, de dyscrasie,8 de cathétérisation de l’artère sous-clavière ou si le diamètre de la voie est supérieur ou égal à 10 French. La nécessité d’un contrôle radiologique à distance est non résolue.
B.Fermeture de l’artère ponctionnée par des procédés non chirurgicaux (plug périvasculaire de collagène, suture percutanée, ballonnement endoluminal, stenting). Ces techniques semblent offrir un meilleur profil de sécurité tout en restant peu invasives. Ce type d’intervention est recommandé dans plusieurs articles.9,10,11 Le choix du procédé dépend, entre autres, du site de ponction.
C.Exploration chirurgicale: le retrait de la voie, et la réparation de l’artère sont effectués par le chirurgien vasculaire.12
En l’absence d’études à ce jour, l’attitude devrait être discutée de cas en cas avec un radiologue interventionnel ou un chirurgien vasculaire.

Compare with this:
" Once the procedure is done, your provider will remove the catheter and close the insertion site. They may close it using either collagen to seal the opening in the artery, sutures, a clip to bind the artery together, or by holding pressure over the area to keep the blood vessel from bleeding. Your provider will decide which method is best for you.

'Strategy' is used for means of closure after cardiac catheterization:
"Upon completion of the large bore cardiac procedure, it is recommended that vascular closure be performed in the cardiac catheterization laboratory or hybrid operating room with cardiac and vascular surgical back-up capabilities (8). Closure strategies currently employed in clinical practice include: 1) Deployment of the Perclose Proglides sutures (1 or 2) which were used to “pre-close” the arteriotomy at the onset of the case; (2) “Post-Closure” using a double-wire approach to facilitate the deployment of two Perclose Proglide; (3) “Hybrid” approach with the combined use of one Perclose Proglide suture and either one Angioseal or Mynx VCD; (4) “Dry closure” with balloon hemostasis of the ipsilateral external iliac artery via radial or contralateral femoral arterial access; or 5) Deployment of the MANTA device (114, 125–127)."

"Manual compression is a non-invasive strategy for access site closure and can be utilized as a first-line option; however, it is time-consuming, labour-intense, strenuous, and bleeding control can be challenging, especially in patients with obesity. The quality of manual compression is dependent on the experience of the cardiac team, and while this might not be the preferred closure method, training of manual compression skills is highly recommended for all interventional cardiologists since it is an important bail out method in the event of any VCD failure.24
The use of compression devices, such as FemoStop™ (Abbott Vascular), should be considered in patients with peripheral artery disease and severe calcifications at the access site since these factors are associated with an increased risk of percutaneous closure device failure, subsequent bleeding, and vascular complications"

'Strategy' would appear to be an option, but other terms can undoubtedly be used too.
